Supposedly, as one beginning to suffer from arthritis, he developed the Tai-Chi for Arthritis form for himself, but he also sells more hard core martial arts videos too. After taking Bob's class, I bought Dr. Paul Lam's Tai Chi for Arthritis DVD. This DVD is lame, especially compared to the live instruction I received from Bob. The DVD itself was poorly organized; it's like they took the VHS and transferred it to DVD with almost no consideration for the power the DVD provides. Moreover, the form is short, including a handful of movements, and Dr. Lam focuses on the mechanical performance of his form. I was expecting some treatment for breathing and chi control. There's a 20-minute block at the beginning where his star pupils give testimonials, various doctor and therapist talk to talking-points about the importance of spinal alignment, working joints to alleviate arthritis, and maintaining muscle tone. Also, the whole form can be finished in about 2 minutes. The warm-up routine took longer! We're supposed to perform Tai-Chi for 20 to 30 minutes, are we supposed to repeat the form 15 times?
OK, I'm done ranting; I'm still glad I bought the DVD. The good points about the DVD are that Dr. Lam presents a new movement by demonstration, then by talking you through it a few times while a pupil demonstrations from different angles. Dr. Lam names the movements, so when you see the list of 9 movements, you know what to do, if you know the movements.
There is a "Part 2" DVD for Tai Chi for Arthritis that expands on these first movements. Basically, you repeat the first one, but switch left and right, then add a new set of movements. Add a couple bridging movements and you end up with a 31-movement form:
Part I
Part II-Repeat, Swapping Left and Right
Part II-New Movements
One more rant: the DVD could have been much better if each new move was it's own chapter. I could have done a "chapter selection" feature to find the "Pushing Mountain" movement, then the skip back to the beginning of the chapter to repeat as needed. But, NO. The whole form is a chapter. I have to fast forward through each new movement to get to "Pushing Mountain". At least I don't have to fast forward through the testimonials....
